Анализ морфолого-анатомической изменчивости количественных признаков хвои в популяциях сосны обыкновенной (Pnus sylvestris L.)

Abstract

In the article the author examines the variability of quantitative characteristics of needle in three chronologically related populations of the Scotch pine (Pinus sylvestris L.). The levels of their individual variability are defined. The author draws the conclusion that the quite informative parameters in the P. sylvestris population are the index of the number of resin ducts to the needle length and the index of the form of needle cross-section.
